Es tr\u00e4gt den Spitznamen \"gefrorener Rauch\", \"fester Rauch\" oder \"blauer Rauch\" aufgrund seiner halbtransparenten Beschaffenheit und der Art und Weise, wie das Licht im Material gestreut wird; bei Ber\u00fchrung f\u00fchlt es sich jedoch wie expandiertes Polystyrol (Styropor) an. Silica-Aerogel absorbiert stark die Infrarotstrahlung. Es erm\u00f6glicht die Konstruktion von Materialien, die Licht in Geb\u00e4ude einlassen, aber W\u00e4rme f\u00fcr die Solarheizung zur\u00fcckhalten. Es hat eine extrem niedrige W\u00e4rmeleitf\u00e4higkeit (0,03 W-m\/m2-K bis hinunter zu 0,004 W-m\/m2-K), was ihm bemerkenswerte D\u00e4mmeigenschaften verleiht. Sein Schmelzpunkt liegt bei 1.473 K (1.200 \u00b0C oder 2.192 \u00b0F). Silica-Aerogel kann die menschliche Hand vor der Hitze eines Schneidbrenners aus n\u00e4chster N\u00e4he sch\u00fctzen.<\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\">\n<p><b>Dies ist eine perfekte Probe f\u00fcr viele wissenschaftliche Laborexperimente.\u00a0<\/b><\/p>\n<p><b>- Tolles Chemie-Geschenk\u00a0<\/b><\/p>\n<p><b>-Verbl\u00fcffendes Wissenschaftsgeschenk\u00a0<\/b><\/p>\n<p><b>-Unterhaltsames Lehrmittel<\/b><\/p>\n<p><b>-S\u00fc\u00dfes Geschenk f\u00fcr den Strumpf, Weihnachtsgeschenk -
